'''Hypertext Application Language''' ('''HAL''') is an [[Internet Draft]] (a "work in progress") standard convention for defining [[hypermedia]] such as links to external [[web resource|resources]] within [[JSON]] or [[XML]] code (however, please note that the latest version of HAL Internet-Draft expired on November 12, 2016.). The standard was initially proposed in June 2012 specifically for use with JSON<ref>{{cite web |last1=Kelly |first1=Mike |title=JSON Hypertext Application Language |url=https://tools.ietf.org/html/draft-kelly-json-hal-00 |publisher=IETF |accessdate=16 October 2018 |date=7 June 2012}}</ref> and has since become available in two variations, JSON and XML. The two associated [[MIME]] types are media type: application/hal+xml and media type: application/hal+json.<ref>{{cite book|last1=Richardson|first1=Leonard|last2=Ruby|first2=Mike Amundsen ; foreword by Sam|title=RESTful Web APIs|date=2013|publisher=O'Reilly|___location=Sebastopol, CA|isbn=978-1-4493-5806-8|edition=First|chapter=7}}</ref>
